1. First create a ddebs.list using:

   
   
   
   
   

   echo "deb http://ddebs.ubuntu.com $(lsb_release -cs) main restricted universe multiverse" | sudo tee /etc/apt/sources.list.d/ddebs.list
   
   




2. Then add the GPG key for ddebs.ubuntu.com:

   
   
   

   wget -O - http://ddebs.ubuntu.com/dbgsym-release-key.asc | sudo apt-key add -
   
   




3. Then run:

   
   
   

   sudo apt-get update
   
   




4. Then install the symbols package using:

   
   
   

   sudo apt-get install linux-image-`uname -r`-dbgsym
   
   

   
   
   

   This is rather huge (>680MB), so prepare for a wait while you download it.
